Hadleigh, Essex
Two-storey rear extension in Hadleigh
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design, get the approvals for and build two-storey rear extensions in Hadleigh and the surrounding area, with one contract from the first survey to building control sign-off.
Hadleigh is covered from our Essex round, including SS6, SS7 and SS8. In Essex we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Hadleigh?
The planning route for a two-storey rear extension in Hadleigh is set by England's householder rules and your council.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Hadleigh like to extend?
Hadleigh mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
